Preservation & Conservation Welcomes New Equipment!

 

Earlier this month, Preservation & Conservation welcomed a new addition to our family: this lovely new digital image capture system from Digital Transitions!  This equipment will be essential in undertaking one of our most ambitious projects yet, the digitization of the 150 scrapbooks in the Keith/Albee Collection.

While our previous overhead scanner, the Zeutschel, has been in use and doing a wonderful job for several years, there has been a need for some time to update this equipment.  Additionally, guidelines for the Keith/Albee NEH grant require that the scrapbooks be digitized at a higher resolution than the Zeutschel is capable of.  For more information on this project, check out our previous blog posts here and here.

OLYMPUS DIGITAL CAMERA

The setup for this new equipment is unprecedented for this department.  The main scanning room had to be cleared out entirely in order to make room for it, and it more closely resembles a portrait studio currently than a typical scanning room.  This new digital reprographic system uses a Phase One digital camera back, taking high quality images of each item.  At 80 megapixels, it uses one of the highest-quality cameras currently available.  The camera itself is attached to an electronically movable column.

New Housing Option for Conservation

Goblet in phase boxWith the recent acquisition of a riveter and a board creaser, the Conservation Lab has a new housing option – phase boxes constructed from sturdy 40 point featuring fore edge closures made of nylon string and riveted vinyl washers. Stronger than a regular 20 point four flap enclosure, and quicker to make than a full clamshell box, these phase boxes can also be modified with Volara foam padding or Ethafoam wells to accommodate objects of various shapes and sizes.Series of plates in phase box

Drying a Wet Book

Interleafing a Wet Book
As a Preservation Librarian, I should know better than to read a book while taking a spa bath. Last week I did just that and dropped my book into the tub. Oops! Luckily I caught it before it was entirely submerged.

Pressing the Damp Book

I took immediate action. I grabbed some copy paper from our home printer and folded the paper in half and interleafed every few pages to start soaking up the water. Then I put the book into a “press” by using a cutting board and cast iron skillets. The press helps by putting a little pressure on the book to blot up the water and to keep the pages somewhat flat. The next day I pulled out the wet interleafing paper and inserted new but in slightly different spots.

Drying Interleafing Paper
I laid out the wet interleafing paper to dry so I could re-use. I repeated this process over several days.

Dried Book Showing a Little Edge Curl
The book is now dry but does show some evidence that it had been wet. If the book in question had been a book of value to me, I would have put the book in a zip-lock bag, stuck it in the freezer, and later taken it to a conservator.

 

Preserving Media

Stacks of different types of mediaIn addition to millions of books, journals, and electronic resources, the University of Iowa Libraries is also the permanent home for film, audio, and video collections.

Projecting an original 16mm film can be risky, and using playback equipment that is dirty or in disrepair can cause permanent damage. Protecting the original is critical; many of our media collections are unique and most are actively degrading. In order to preserve this content and make it accessible to we need to digitize it.

I recently traveled with local historian and collector Mike Zahs to visit The Media Preserve, the vendor we contracted to digitally reformat some of Iowa’s most precious “time-based” media collections.

The Media Preserve is staffed by enthusiastic and knowledgeable professionals with many of experience working in the film, video, and recording industries. The studios at The Media Preserve are designed to minimize risk to customer assets, such as power surges, lightning strikes, or electromagnetic interference. Their studios are fully equipped to read and play back every type of time-based media content imaginable.

For common consumer media like VHS and ¾” Umatic tapes, the digital transfer process has been engineered to allow a small number of staff to oversee the digitization of multiple assets at once, thereby lowering transfer time and cost to their clients. In addition, The Media Preserve has a film preservation lab equipped for cleaning, repair, and high-resolution scanning of film. Their film preservation staff recently digitized half a dozen of Mr. Zahs’ badly degraded 35mm nitrate films created in the first few years of the 20th century.
